MSN2100-CB2F Mellanox Ethernet Switches Half Width 10/25GbE And 100GbE

MSN2100-CB2F: High-Performance 100GbE Open Networking Switch

The MSN2100-CB2F is part of the NVIDIA Spectrum SN2000 Series, a next-generation open Ethernet switch designed for modern data center leaf, spine, and super-spine deployments. Delivering 1.6Tb/s throughput with 16x100GbE QSFP28 ports, this switch offers exceptional performance, ultra-low latency, and advanced telemetry capabilities. Ideal for cloud, AI, and storage environments, it supports multiple open network operating systems and offers full hardware programmability.

Key Features

• 16 x 100GbE QSFP28 ports supporting 10/25/40/50/100GbE speeds
• 1.6Tb/s throughput with 2.38 billion packets per second (Bpps)
• Cut-through latency as low as 300 nanoseconds
• 16MB fully shared dynamic packet buffer
• Support for Cumulus Linux, ONYX, SONiC, and ONIE-based OS options
• Hardware-accelerated telemetry with WJH (What Just Happened?)

Core Technologies

The MSN2100-CB2F is powered by the NVIDIA Spectrum ASIC, enabling advanced features such:

• VXLAN routing and bridging
• RoCE (RDMA over Converged Ethernet) support for GPU-direct workloads
• In-band Network Telemetry (INT) and streaming telemetry
• Deep packet inspection up to 512 bytes
• Programmable pipeline for custom networking functions

How It Works

The switch operates in cut-through mode to minimize latency. The shared packet buffer dynamically allocates memory to congested ports, preventing packet loss. Hardware-based telemetry collects real-time data on network performance, queue depths, and events, providing deep visibility into traffic patterns and issues.

Applications

The SN2000 series switch is ideal for:

• Cloud data centers and hyperscale environments
• AI and machine learning clusters
• High-performance storage (NVMe-oF, HyperConverged)
• Financial trading and low-latency applications
• Campus and enterprise core networks

Specifications

Advantages

• Superior buffer management prevents packet loss under congestion
